As of today, they have received 400 registrations. The maximum registrations for this year will be capped at 800.

Although the convention website states that "a two nights' deposit is required at the time reservation is made," I do not believe that an actual deposit has to be immediately paid if you reserve with a credit card. There appears to be some discrepancy between what the website says versus what the hotel will say in regards to the room deposit and the cancellation policy. If this concerns you, I suggest that you ask about these details when you make your room reservations.
